摘要:
The present invention provides a novel production process for an ethylene oxide resin, in which, when the ethylene oxide resin is obtained, it is arranged that the resin should contain no antistatic agent, and further its water content is also easily controlled in not more than a definite amount, and the thermal damage of the above resin is prevented, and besides, the reduction of the cost can also be actualized. The production process for an ethylene oxide resin, according to the present invention, comprises the step of carrying out devolatilization of a solvent from a polymerization reaction liquid containing the solvent, thereby obtaining the ethylene oxide resin; with the production process being characterized by arranging that: after the devolatilization, the resin should have a solvent concentration of 0.01 to 30 weight % and a water content of not more than 200 ppm, and the resin should contain no antistatic agent.

摘要:
A gel-like resin molded object composition prepared by forming a resin molded object comprising allyl isothiocyanate and a resin base into a gel is provided. This gel-like resin molded object composition is used as a gel-like repellent composition or a gel-like antimicrobial and antifungal composition. The content of allyl isothiocyanate is within a range of more than 20% by weight and not more than 85% by weight based on the total weight of the gel-like resin molded object. The rubber hardness of the gel-like resin molded object is within a range from 0.1 to 100. The gel-like resin molded object of the present invention can be formed into a bulk, sheet, film, particle, powder or coating. The gel-like resin molded object can be used as a volatile gel-like packaged drug obtained by filling a container partly comprising at least a packaging material, through which a volatile gas of said volatile drug can permeate, with a drug mixture containing a volatile drug and a gelling drug, and gelling the drug mixture.
